2000 - … Teaching Agronomy in Bordeaux Sciences Agro and researching on Potassium Plant Nutrition in INRA

1998 PhD Graduation "Non point source P transfert at a small rural catchment scale", Univ Paris VI & Ecole Polytechique de Lausanne

1994 Rural Engineering Graduation (Ecole Polytechnique Fédérale de Lausanne, Suisse). Soil and Water Specialisation

Actual Skills

Research question: What is the impact of K deficiency on growth and development of crops? – How do K nutrition help plants to mitigate water stress? – How could the nutrient fertilization recommendations be more process-based, while being useful for farmers?

Scientific Expertise: Biogeochemistry of major nutrients – Evaluation of minerals bio-availability – Crop mineral nutrition – Potassium and plant ecophysiology – Water stress and plant ecophysiology

Technical skills: Soil agricultural potentialities – Soil Analysis and interpretation – Hydroponics – Gas exchange measurements at leaf scale – Plant water status measurements (Scholander chamber, leaf surface temperature measurements, …) – Roots hydraulic conductance (High Pressure Flow Meter) – 13C plant labelling.


Biogeochemistry – Ecophysiology – Dynamic Modelling (STELLA ®) – Management of Inputs in agriculture (Water, Minerals, Organic matter) – Crop system designing – Relationship between Agriculture and Energy – Diffuse non-point source pollution sampling during field surveys – Agroforestry
